fix installer VERSION override tags

[charlesHetterich]

Summary

• preserve explicit VERSION overrides verbatim so dev/<branch> release tags are not prefixed with v
• keep v normalization for implicit latest/jsDelivr stable release resolution
• add a patch changeset for the installer fix

Verification

• bash -n install.sh
• zsh -n install.sh
• git diff --check
• simulated override resolution keeps dev/rh/fix-pagination unchanged
• simulated stable fallback resolution maps 0.19.0 to v0.19.0
• checked the real dev/rh/fix-pagination asset URL resolves while vdev/rh/fix-pagination 404s
